Janka Hardness Scale

What Is The Janka Hardness Scale?


The Janka Hardness Scale is a standard wood hardness scale for measuring the denting and wear resistance of a sample of wood. Samples of wood are tested by driving a steel ball with an 11.28 mm diameter into the wood and measuring the force it takes to do so. The result is a relatively uniform measurement of the wood sample’s durability.

Our Products and ratings


We have utilized the Janka Hardness Scale for grading our flooring options in order to provide you with the most accurate guide to each wood sample’s resistance to wear and denting. Each test results in a numerical rating for the sample of wood; higher numbers indicate a more durable and wear-resistant wood sample.
